Invader – passion in perfection
Box-frame made to measure, riding comfort with individuality. When our experts take matters in hand, the eyes of discerning wheelchair users light up.
Your measurements set the standard
For good reason: Individualists demand a wheelchair for active use which is perfectly suited to them. For your Invader, we build every single length and angular dimension to your specifications. The entire seat tube can be shaped to your anatomy and the back upholstery can be perfectly adapted to your body as well. The sporty shape of the frame combines extreme sturdiness with a low net weight – Made in Germany.
Hard, harder, Invader
We fabricate the box-frame from a single tube of 7020 T6 aluminium, the hardest of all weldable aluminium alloys. Even the caster fork is manufactured from one piece, and the footrest can be welded as well. The result: Maximum stability, an extremely low weight and minimum maintenance.
So why compromise?
